RELAY.

Specification of Letters Patent.

Patented July 27, 1909'.

Application filed May 12, 1908. Serial No. 432,335.

To all whom it may-concern:

. it known that I, JEAN F. WEBB, J12, residing at Denver, in the count y of Denver and State of Colorado, have invented certain new and usefulImprovements in lielsys, of

which the following is s specification.

My invention relates to certain new and useful improvements in electro-nmgnotic rclays for use in connection with signnlingcin cults, semsplwre operating circuits, tele- A graph circuits and the like, wherein it is desired to close a local .circuit or circuits control of a mum being hereinafter termed the keeper for the armature).

More sul-ordinzn cly my inven tion enil od those novel details of constructhm, comhinetion and nrrnngement ol' ports all. ol which will he lirst descrihcd in detail, and lhen he specifically pointed out in the npponded claims, reference hoinc; hnd to-thc accompanying drawings, in which:

Figure 1, is a perspective view ot one form of my invention. Fig. 2, is a side elevation thereol'. Fig. 3%, is :1, top plain view thereof. his. 4, is an end clcvhtion thcreol'. Fig. 5, is n perspective view of o. slightly modified form -ol' my invention. Fig. (5, is a side elevation thorcol'l licl'erriirc now to the accompanying drowing's in which like letters and numerals of ref ercnre indicate like parts in all olthe figures,

1 represents my improved relay which com prises :1 best: 2, preferably constructed of insuh ting nmterisl to which the {tr-nurture hearing support 3 is secured in any approved manner, the bearing support Shaving hesringpr lulcrum screws 4 on which the ar nurture 5 is mounted. Theermrtture ,5 consists of a substantially vertically disposed body 5" and s shorternrm 5 arranged at right angles to the body 5 with hich-the l'ulcrun: o1 pivot screws "4 contsct Y i Fin. 7. is n to .ilnin view thereof.

At the bottom of the armature is s contact block 6 which serves to short-circuit the fixed contacts 13-14 'ol" :1 local circuit 15 which includes a signal 15 and n source of electric energy 15*, as shown in Fig. 2 of the drawings. The armature 5 also carries s stepped block 7 having the steps 7 ""-7", and the block 7 is insulated from the armature 5, as indicated in the drawings. l

The keeper or locking member 12 is pivoted on screws or pivot members 11 in a support 10 that is secured to the hose 2, and the keeper ].'2 consists of a short heel portion 12 adapted to cooperate with the stepped block 7 nnd a. longer lever portion 12 which is adopted to he moved to release the armature from its circuit closing position.

Any suitzihle moons .nmj," he used to move the lever 12, such as n reciprocating psrt oi some ineclmnicnl device tlnttis opcreted hy the local circuit 15 or the lever 12" may he moved by hand.

closing position l the msin operating msgnets Qwhieh are mounted on it support 8 that is secured to the hose 2 and which are electrically I connected in the local circuit 9* 9* end the circuit closer 9.

When the srmsture is moved to its circuit closing position h the main magnets 5), the heel 12? of the keeper '12 drops, o reason of the gravity of the keeper 1.2, onto stop 7" and holds the nrmsturc 5 in'its circuit closing position. \fhen the keeper 12 is moved to bring); the heel 12 off of the step 7 into nlineincnt with'the step 7", the armature 5 heceuse of its pivotal inonnting (as indicated inthe drmving's) swings hack into its circuit gravity and the weight of the whole of keeper 12 when the heel 12 rests on.the step 7 In Figs. 5'to 7 inclusive, I have shown. it slightly modified term of my invention in which the'keeper 12 is in the nature ol'n plane plate 12 whose heelportion 12 adapted to cooperate with the stepped block 7 and the plate 12* is pivoted on the pins 11 in the frame 10, as was the keeper 12 of the form shown in Fig. 1, ol' the drawings.

, In the forms shown. in Figs. 5 to 7 inclusive,

I have shown eleetro-magnetic means for openingposition by the action of gravity and" is held in that position by reason olits' The nrmnture 5 is moved to its circuit which includes the source of electric energy operating the keeper 12 which acts as the armature forthe magnets 16 that are mounted on the support 3 and electricallyeonnecte" in a releasing circuit 17 which includes a source of electric energy 1.7 and a circuit closer 17 of any approved type, so that by closing the circuit closer 17 the magnets 16 will beenergized to lift the keeper 12* (their armature) out of the step 7 and permit the armature 5' to swing to its circuit opening position by gravity at which. timethe keeper 12 will rest on the step 7 and when the circuit 17 is opened by opening the circuit closer 17 and denergizing the magnets 16,

the'keeper l will drop upon the step 7*.

In order to aid the action of gravity a coil spring 18 may be provided, ii found desirable or necessary.

From the foregoing description taken in connection with the accompanying drawings, it is thought the complete construction, operation and many advantages of my invention will be readily understood by those skilled in the art to which the invention appertains.
